The study to explore the development of these abilities with age, and called "Development
of the conflict detection during the reasoning - Decor" will take place at CYCERON center
and will include two groups of 22 participants: adolescents and young adults (N = 44).
More specifically, this study aims to compare the changes in the brain of adolescents and
young adults when conducting reasoning tasks for which there may be a cognitive conflict.
Both groups of participants then spend an MRI (Magnetic Resonance Imaging) focused on the
brain and in which they will carry out two classic tasks covering the main areas of
reasoning (probabilistic and economic). Each of these tasks will be manipulated to
include, or not, of making information call intuition to create or not a conflict between
the correct answer (logic, normative) and biased response (intuitive, heuristic). Because
of the major implication of this brain region in cognitive inhibition processes [of
intuitive answer], measured brain activity in the anterior cingulate cortex (ACC) during
both tasks version "with" or "no" conflict will be compared between groups. To better
understand the links between the development of the CCA from adolescence to adulthood and
conflict detection, activity measurements will be correlated with a part in morphometric
measurements taken from the same area (volume Substance Grise - SG; characteristics of
cortical sulci) and secondly to cognitive measures (executive functions - inhibitory
control). This cross-sectional study focused on two age groups: 11-15 years and 19-25
years. For each age group, the participation of men / boys and women / girls will be
balanced up.
